We have much pollution around us now.It is not only harmful to our physical heath,but also our mental health.People can be very stressed under such an enviorment as we have today.Morever there is another public problem--traffic.People are easily get annoyed by the heavy traffic,also by the noise it produces.In my opinon ,the goverment should do what they can to change those things.
